APPARATUS FOR MAKING ORNAMENTAL PAPER.

To all whom it may concern:

Be it known that I, ERNST MAHLER, a citi zen of Austria, (who has declared his intention to become a citizen of the United States,) residing at Neenah, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Apparatus for Making Ornamental Paper,,of which the following is a specification.

My invention relates to improvements in ornamental paper and apparatus for making same, an it is of particular value as applied to the making of finished paper directly, without the'necessity of printing or otherwise treating the aper after it leaves the paper-making mac iinery. A separate application has been filed by applicant on the ornamental paper and process for making same, and bears filing date of December 21, 1917., and Serial No. 208,294.

I The salient objects of the invention ai'e to produce an improved ornamental paper having color applied thereto in such manner as to produce an ornamental finish having distinctive high light and shadow markings; to produce a paper of the class described in which the high lights may be of one color and the shadow effects in another color; to provide improved apparatus for producing the said classes of ornamental paper; to

provide an 'apparatus of the class described which may be utilized in connection with ordinary paper-making machinery without the necessity of extensive re-designing or reconstruction of such machinery; to provide an apparatus of the class described which will result in the production of a paper. having mechanical characteristics comparable with those possessed by ordinary uncolored paper; to provide an apparatus which is capable of continuous operation; to provide an apparatus which shall' be capable of rapidly, economically, and efliciently imparting to the paper surface the desired ornamental appearance: and, in geiieral, to -provide an improved paper and apparatus for producing same of the character referred to.

As an example of one method of practising my invention, I utilize an ordinary paper-making machine having the usual Four- Speclfieation of Letters Patent.

drinier wire and associated apparatus. Preferably, the mechanism which imparts the customarylateral shake or vibratory movement to the Fourdrinier wire is-throWn out of commission so that the motion of the belt is a simple straight line traveling is sufiiciently set or formed, 1 direct-upenits upper surface a series of air-brush sprays of liquid color, the effect of which is to embed the color in the projecting roughiiesses of the paper and thereby produce the desired ornamental finish.

' Describing the apparatus, and referring particularly to Figs. 1 and 2, it will be observed that the machine as a whole is mountventing spreading of the pulp which is fed onto the Fourdrinier wire over the table or distributing box 29 adjacent the rear pulley 23. The suction boxes 30, 31, and 32 are of usual construction, which also applies to the couch roll 33, while the rolls and associated apparatus for finishing the formed web 34 are of customary design and operate upon the paper in the ordinary manner; they therefore need not be shown or described further. The usual mechanism for imparting side shake to the Fqurdrinier wire is not shown in the drawingsfor the reason thatsuch mechanism is dismantled or thrown out of operation when practising my invention.

On a set of standards 35 and-36 is secured an iron frame work 37 which extends over the machine from side to side. On the said frame work 37 is preferably secured a Wooden platform or runway 38 for the convenience of the operator in making the various adjustments to the spray apparatus. The ends of said frame work 37 preferably comprise a pair of longitudinal members 39 and 40 (see Fig. 2) which are slotted, as shown at 41, 42, 43, and 44, in order to slid-ably receive the clamping bolts of a pair of pedestal bases 46 and 47. The said pedestal bases 46 and 47 constitute base mountings for the vertical column rods 48 and 49 which carry the spray apparatus.

On each of the.columns 48 and 49 is a pair of clamp mountings 50 (see Fig. 3). Said clamp mountings each comprises a split clamp portion having a pair of clamping screws 51 for securing the clamp 50 to the vertical column 48, and it is also provided with an offset horizontal column portion 52 aperiured to receive one of the hori zontal supporting tubes 53. The horizontal column portion 52 is split to clamp around the horizontal tube 53 when the clamp' g screws 54 (see Fig. 2) are screwed up.

By reason of the slots 41, 42, 43, and 44, the columns 48 and49 may be clamped in such position as to bring the rods 53 in any desired inclined position wit-h reference to the travel of the paper web. Also, by means of the double clamps 50, the said rods may he slid up and down the said columns 48 and 49. Also, the spacing of the said columns 48 and 49 may be readily changed if desired.

The top rod or supporting tube53 conupper tube 53 and being secured thereto by clamps 57 (see Figs. 3 and 6). Said clamps 57 are preferably split, as shown at'58, in order topermit adjustment of the said parts 57 alon the tube .53, tightening being effected by t ewing screw 59. That said ply of air is maintained at a substantially constant premure. The said mains 55 and 56 are fitted with T connections, as at 62 and 63, a pair of connections, for-instance as shown in Fig. 3, being adapted. to feed a pair of flexible hoses 64 and 65 which fit over the suitably shaped ends. of short branch ipes 66 and 67. The lowerends of said oses 64 and 65 fit over the suitably shaped ends of the branch pipes 68 and 69, said pipes communicating with a color-control valve 70 and an air-cock 71.

The control valve 7 0 and the air-cock 71 are screwed onto the ends of the pipes 72 and 73, and by means of unions 74 and 7 5 are connected to short pipe sections 7 6 and firmly in position in said arm.

The upper portions of the color pipe 72 and air-pipe 73 are,;in the present instance, mounted and secured in a special form of universal clamp designated as a Whole 83, so organized as to allow of adjustment of the nozzle to deliver the jet of color spray in any desired direction with reference to the travel and surface pf the moving paper web. Said clamp 83 comprises a sleeve clamp 84 .bored out to receive the lower tube 53, and split, as 'shown at 85 in Fig. 5, accommodating a pair of clamping screws 86, whereby the said clamp may be moved as a Whole along the lower pipe 53, or revolved around the axis of the said pipe The saidsleeve 84 is' also provided with a lower central boss 87, suitably bored out to receive the mating portion of the swivel boss 88 constituting one end -of the casting 89. The casting 89 may be clamped in any angular position with reference to the boss 87 by means of the clamping"- screw 90. The other end of the casting 89 is bored out to fit the corres ending circular end 91 of the casting 92, w ereby the member 92 may be rotated into any angular position with reference tothe casting 89. Clamping of the said casting 92 in such position .is effected by means of the cap screw 93. The pipes 72 and 73 are secured to the member 92 in any desired osition by means of a resilient strap yo e 94 perforated to receive a central clamping screw 95, and having its ,ends 96 and 97 suitably shaped to fit the curved surfaces of the said pipes 72 and 73.

If it be desired to incline one or both of the supporting tubes 53 to the horizontal, this may be effected by reason of the swivel joint 98 interposed between the clamps 50 and 52, clamping of said swivel joint 98 in any desired position being effected by means municates with a horizontal bore 103 formed in said casting and into which is inserted a horizontal jet tube 104 having its open outer end flattened, as shown at 105, in order to provide a thin horizontal slot-like jet 100 immediately beneath the color slot 102. The tube 104 is secured in the open outer end of the bore 103 by means of a cap 1.07 having a tapered threaded aperture arranged to screw over a correspondingly tapered and threaded nose 108 on the casting 80. Said nose 108 is preferably slitted at three equidistant points, so that it will collapse slightly and grip the tube 104 when the threaded cap 107 is screwed home.

The operation of the apparatus is practically self-evident, in View of the drawings and the above description. A supply of uncolored pulp flows onto the upper surface of the Fourdrinier wire web and deposits thereon, forming a web of paper which, during its movement with the Fourdrinier wire, is

gradually freed from water which is drained through the wire by gravity and by the suction due to the said wire passing over the suction boxes 30, 31, and 32. By reason of the fact that the usual side shake is' not present, the pulp, however, does'not deposit into uniform fiat pulp, but has a rough upper surface having miniature peaks and valleys instead of being uniformly flat, as is the case when the side shake is present.

The spray apparatus, as shown best in Figs. 1 and 2, is preferably adjusted in such position that each jet ofspray 109 strikes the surface of the paper at as flat an angle as possible, thereby causing the particles of color to strike only the tops of the peaks .or roughnesses on the surface of the newly formed paper web. In the event that the paper is of considerable width, it may be found desirable to use more than a single spray. For instance, in Fig. 2, I have shown a set of three sprays 10 110, and 111 which overlap and merge into each other, thereby bcovering the entire area of the traveling we While the. color is being" sprayed onto the surface of the moving paper web, the latter is of course in a damp and uncompacted condition; but when the web has passed under the couch roll and traveled through the finishingor calenderin'g rolls, the web may be thereby flattened or compacted to produce a paper having a uniform smooth and level surface and of the desired texture. Such finished paper, however, will be found to possess the same characteristics with reference to color and general appearance as were imparted thereto by the color-spraying apparatus.

The samples accompanying this application illustrate in a general way the characteristic appearance of single-color and duplex-color finished paper manufactured according to my invention.

If desired, I may with my improved process and apparatus produce two-color paper.

If such is desired, I arrange the sprays "of the two different colors so that they cross the line of travel of the belt from opposite sides and in opposite directions, so that one side of the peaks in the paper web is coated with one color while the other side of the peaks is coated with a different color. Beautiful effects may be produced in this manner.

If desired, slightly different forms of jets may be used. For instance, in Figs. 10 and 11 I have disclosed other forms of caps 101 and 101". In the caps 101 I utilize a slot 112, but the lower end of the slot 112 docs not communicate with the interior of the cap 101. except through a series of three small circular apertures 113. The cap 101 is the same as the cap 101*, with the exception that the slot 112 is not present, the color simply issuing directly from a set of three apertures 113.

The described details of operation and construction are merely illustrative of the invention, the scope of which should be determined by reference to the appended claims.

I claim- 7 1. In a device of the class described, the combination of a traveling Fonrdrinier wire to support a paper web while forn'iing, and means for spraying color on the upper surface of said web while maintaining a straight line movement of said wire, free from lateral shake.
